Can the pipeline flow rate be calculated from the pipe diameter and pressure?

I would be extremely grateful if you, senior colleagues, could help! !
No, for example, in a 2-inch pipe containing 1, 2, 3, 4, or 5 kilograms of immobile medium, the flow rate will be 0. At the very least, you need to measure flow using differential pressure, and different throttling elements have different flow coefficients, so it’s impossible to calculate it.
There are too many missing conditions; you need to provide many variables
It probably won’t work; you also need to know the pressure difference...
The flow rate of a pipeline can be calculated based on the pipe diameter and the pressure difference across the pipe section.
In the case of a gas flow blocked by a restriction, throttling elements such as orifice plates, nozzles, or Venturi tubes are used; the flow rate can be determined based on property data, pipe dimensions, and upstream pressure. Just like sonic nozzles, it can be used as a standard flow meter to calibrate other devices. @jiaguoyun
